Tri-square

From Team 449 Wiki

A tri-square is a tool for the purpose of making accurate measurements and marks when working with wood or metal. It consists of two perpendicular straight sections, one of which may serve as a ruler. As its name would suggest, it's purpose is literally "trying the square", or determining if something is at a right angle. Tri-squares are very important for the accuracy required in making cuts and connections for the parts of the robot.
